Default Re: Quadro FX 880M Stability Problems

Interesting observation. Does it whine only while actively changing the brightness, or does it continue to whine after the brightness is changed?

There are quite a few differences between the VT and and an X session... fewer if you are using a framebuffer VT, but differences nevertheless. I don't know off the top of my head how those differences would affect brightness changes. Most likely it might have something to do with the timings the display is driven at.

The problem with the brightness controls is that the driver doesn't know to enable brightness controls automatically, so a "fixed" driver will not behave differently than manually enabling them in your xorg.conf with the current driver version.
